Abstract: 120,196. Maynes, H. L. Oct, 25, 1917, [Convention date]. Addition to 116,084. Selective punching-machines.-The camera provided with means for marking films &c. by perforation described in the parent Specification is provided with means movably mounted thereon for gripping the film and means for moving the gripping means to bring successive portions of film into position to have identification marks impressed upon them. The perforating mechanism comprises an operating member 43, Figs. 2 and 5, in which the perforating punches are mounted and provided with a notch 46 for receiving the edge of the index plate 51, Figs. 2 and 3, and a projection 47 fitting within an inclined groove 42 formed in the cylindrical part of a pivoted lever 40 whereby movement of the lever first causes the operating member to be depressed and will then depress the index plate to actuate the punches selectively. The index plate is of the form described in the parent Specification, but in a modification a single plate provided with projections to engage the punches may be provided. A pawl 57 slidably mounted in guides 58 and acted on by a spring 59 engages notches in the index disk to hold it in the correct position while perforating the film, and may also serve to indicate which letter is being perforated, or a separate index may be provided for that purpose. Mounted on the back of the camera are guideways 70, Fig. 10, one of which is provided with index marks 71, the spaces between the marks corresponding to the space between successive perforations and being utilized to adjust a film so that the inscription may be placed symmetrically. Sliding in the guideways is a base piece 72, having a curved portion to fit the curved end of the camera back to which is riveted a resilient gripping member 73 having three spring tongues, the outer ones 74 serving to grip the edges of the cut film while the middle tongue 75 is bent as shown at 77, Fig. 11, to engage the ratchet teeth of the rack 81. A lifting lever 78 engages beneath the raised parts of the tongues 74 in order to raise them for the insertion of the edge of the film. The rack bar 81 is mounted to have a limited longitudinal movement and has attached to it a pin 85 which is engaged by a slot 87, Fig. 5, in the slidably mounted link 86 which is operated by the pin 89 on the lever 40 engaging a curved extension 88. The arrangement is such that, on the rotation of the lever 40 through 90 degrees, the rack bar is reciprocated and moves the clip 74 one space forward before the film is perforated. When the camera is used in the ordinary way, the clip is slid to one side out of way of the roll film. In order to indicate the correct amount of movement to space the perforations correctly on a roll film, the film bears against a roller 66, Figs. 3 and 10, bearing index marks. In place of this the film backing may have a series of marks showing through the sight opening 62, Fig. 3.

Filed: 1929-04-16
Abstract: 309,920. Telefunken Ges. f³r Drahtlose Telegraphie. April 17, 1928, [Convention date]. Directive signalling.- In a directional aerial system A comprising one or more reflector wires B, both systems are connected to a common feed-line K and associated tuning- elements L, C. In this way the whole reflector system can be tuned to cooperate in proper phaserelation with the main aerial A. Or, if the reflector is energized directly from the power supply, the tuning elements L, C can be adjusted to ensure the correct phase relationship, having regard to the separation between A and B and the working wavelength. Amplitude adjustment is effected through the coupling M. As the system is symmetrical, the main directional effect can be reversed, the aerials A thus acting as reflectors. Tuning may be effected by suitable extensions of the feed-lines instead of using definite inductance coils and condensers such as L, C.

Title: Method of repairing the surfaces of ferrous metal bodies
IPC: B23P6/04
Filed: 1937-04-26
Abstract: In repairing ferrous metal bodies by securing a coating or filling of metal thereon, e.g. in filling depressions or dents in an automobile body by means of sprayed metal, the ferrous metal surface is cleaned by abrasion, rubbed with a composition comprising an abrasive, hydrochloric acid, mercury bichloride, zinc chloride, copper sulphate, and metallic mercury until a uniform bright coating is obtained, and is then coated or filled by spraying lead or lead alloy thereon, the final coating &c. being sanded down flush with the surface of the article and then painted if desired.  The preliminary coating composition may be made up in two parts, one containing the metallic mercury, the mercury bichloride, and the abrasive, which may be a mixture of quartz sand and the abrasive known under the Registered Trade Mark "Crystolon," and the other being an aqueous solution of the other components.  The two parts may be mixed immediately before application or the aqueous solution may be applied first.  The composition is preferably applied with a wooden paddle and rubbed in with a felt pad.  A copper coating forms on the ferrous surface which then combines with the mercury to form an amalgamated coating which also includes zinc deposited from the zinc chloride. The spraying of the lead or lead alloy is preferably effected by the spray gun described in Specification 491,172, [Group XXIX], the nozzle being moved with a circular motion first around the outer edge and then towards the centre of the area to be coated, until the metal has been built up above the level of the surface of the work.  The coating is then sanded down to the desired level.  If respraying is necessary, e.g. if after sanding insufficient metal is found to be present, the surface is rubbed again with the preliminary coating composition several times and with considerable pressure and the coated surface immediately resprayed.
